Helicopter Unit Range

A question for experienced war players: I declared on a level 7 C3 9500 miles away, planning to take it by conventional missiles. After I landed the special forces and painted the country I made an attack to the capital and had big casualties (120 batteries). It wasn't the Stealths, but a defense helicopter wing that did the damage. In the Documentation, however, it clearly says that helicopters have a maximum range of 7000 miles. My batteries should be comfortably out of range. So what went wrong? Any clues?

The documentation is wrong... you cant 'out-range' the helis. That scenario has been tested many times over the past several years and the helis always reach you.

Bummer aint it?

Sure is...Thanks for the answer anyway Jason.

Btw, isn't it hilarious to think of helicopters actually responding to an attack 9500 miles away? It would take them something like 2 days to go there and another 2 to return LOL!
